Rapid detection kit of lemon yellow in food

Abstract

The invention discloses a rapid detection kit of lemon yellow in a food. The rapid detection kit comprises a detection card used for rapidly detecting the lemon yellow in the food and a lemon yellow pretreatment reagent, the detection card comprises an absorbent paper, a sample pad used for placing a sample treatment liquid, a gold marking binding pad, a detection line, a cellulose nitrate membrane and a quality control line, the sample pad gold marking binding pad, the detection line, the cellulose nitrate membrane and the quality control line are sequentially arranged on the absorbent paper, and the detection line coats lemon yellow OVA conjugate. When the rapid detection kit of lemon yellow in the food is used, a sample to be detected is fully and uniformly mixed with the lemon yellow pretreatment reagent to obtain a solution to be detected, the solution to be detected is dripped on the sample pad, and the addition amount of the lemon yellow in the food is rapidly detected through using an immunochromatography principle. The rapid detection kit has the advantages of simplicity in operation, short detection time, and great increase of the working efficiency, is suitable for onsite rapid detection of the addition amount of the lemon yellow by various enterprises, detection mechanisms and supervising departments, and is suitable for the rapid detection field.

Description

technical field [0001] The invention relates to the field of rapid detection, in particular to a rapid detection box for tartrazine in food. Background technique [0002] Lemon yellow is also known as tartrazine yellow, acid yellow, hydrazine yellow. The chemical name is 1-(4-sulfonic acid phenyl)-4-(4-sulfonic acid phenylazo)-5-pyrazolone-3-carboxylic acid trisodium salt, which is a water-soluble synthetic pigment. The appearance of edible tartrazine is orange-yellow powder, slightly soluble in alcohol, insoluble in other organic agents. The reason why tartrazine can be used as a food and drug dye is because it is relatively safe, basically non-toxic, does not accumulate in the body, most of it is excreted in the original form, and a small amount can be metabolized, and its metabolites have no toxic effect on humans . Symptoms of an allergy to tartrazine typically include: anxiety, migraines, depression, blurred vision, asthma, itching, weakness, hives, choking sensation...

AI Technical Summary

Problems solved by technology

[0003] At present, the operation of detecting tartrazine is cumbersome and the detection time is long. It is not suitable for the on-site rapid detection of dexamethasone residues by various enterprises, testing institutions, and supervision departments, which greatly limits the scope of application and reduces work efficiency.
